摘要
对辐照灭菌的酸性黄壤（ｐＨ值５．６）中的茶苗（Ｃａｍｅｌｌｉａｓｉｎｅｎｓｉｓ）接种ＶＡ菌根真菌（Ｇｌｏｍｕｓｅｐｉｇａｅｕｍｇ），并追施￣（３２）Ｐ－过磷酸钙和￣（８６）Ｒ＿ｂ－氯化铷，（代替￣（４０）Ｋ－氯化钾），生长２１０天后测定表明，菌根侵染率，真菌＋￣（３２）Ｐ为５２．９％和真菌＋￣（８６）Ｒ＿ｂ为５１．９％，且与茶树根际土壤微生物再生数量呈正相关。茶树株高分别是对照的２倍和１．９倍，地上、地下部干重分别是对照的２．３倍、２．２倍和３．０倍、２．７倍。对￣（３２）Ｐ和￣（８６）Ｒ＿ｂ的吸收量分别为对照的４．３倍和３．６倍，对Ｍｇ，Ｆｅ，Ｚｎ，Ｃｕ等元素的吸收率高于对照１．６～２．８倍。叶片叶绿素总量、根系脱氢酶、土壤磷酸酶活性均明显高于对照。
n a pot experiment on red soil(pH 5.6) tea(Camellia sinensis)seedlings were inoculated withVA mycorhiza and dressed wity￣(32)P-rock phosphate or￣(86)Rb-chloride in place of￣(40)K-chloride(VAM+￣(32)P and VAM+￣(86)Rb ).Investigation made 210 days after the treatment showed that VAmycorhLa infection percentage was positively correlated with the number of microbes regenerated inthe root zone of the seedings,being 52.90% and 51.91%,respectively, for VAM+￣(32)P and VAM+￣(86)Rb. Plant height was 2 and 1.9 times that of the control,day weight of the shcot and the rootwas 2.3 and 2.2 times and 3.0 and 2.7 times, and the uptake of￣(32)P and￣(86)Rb was 4.3 and 3.6times that of the control.Their uptake of Mg,Fe,Zn,and Cu was 1.6～2.8 times greater than thecontrol.Total chlorophyll,dehydrogenase activity in the root and phophorylase activity in the soilwere significantly higher in the treatments than in control.
